How to find the coaxiality of the twin-screw extrusion granulator barrel?
Thread Content
Can someone please explain how to find the coaxiality of the barrel of a twin-screw extrusion granulator?
It is parallelism. I would also like to explain how to detect parallelism and how to adjust it.
Why measure such a rough body? There is no need. Just install the bearing box, etc. and then measure the parallelism of the rotor.
The first picture is the old cylinder, and the second picture is the new one. The cylinder has ten sections in total. How to measure the parallelism after assembly? The rotor is cantilevered and there is no need to measure parallelism.
Is it still necessary to find the parallelism of the cylinder? Check the instruction manual to see if there are any regulations. Just make sure the screws don't scratch the barrel wall or collide with each other during operation. Is the extruder made by Coperon or Nippon Steel?
What is the clearance between the rotor and the housing? If it really doesn't work, you can apply red powder and turn the car to see the contact points, but 10 knots is a bit of an ink job.
Sir, how did you check it later?
